Operation Berlin faces carrier interception

The surviving German 15-inch ships and carrier would attempt a fast Atlantic sortie through the North Sea. If Britain or Norway retains northern bases, radar-equipped maritime patrol aircraft can report the breakout while carrier groups wait behind the search line. British formations built around three capital ships and two carriers seek to combine against the smaller German group, although keeping that strength continuously at sea requires a much larger rotation pool. Without Norwegian bases, the raiders may reach the Atlantic as they did during Operation Berlin, but the greater number of carrier-led hunting groups still makes detection likely. British doctrine, demonstrated at Matapan, uses air attack to slow or blind an opponent before fast capital ships close for decisive day or night gunfire. The Germans might escape, but they now face a faster battle fleet and the approaching Lion class rather than the historically limited pursuit force.
